4.25*5.24*1.52*2.51的简便算法
4.25*5.24*1.52*2.51的简便算法
4.25*5.24*1.52*2.51
=4.25*8*0.19*1.31*4*2.51
=34*0.19*1.31*10.04
=6.46*1.31*10.04
=8.4626*10.04
=84.626+0.338504
=84.964504
4.25*5.24+1.52*2.51
=(4+0.25)*(5+0.25-0.01)+(1+0.5+0.02)*(2+0.5+0.01)
=(4*5+4*0.25-4*0.01)+(0.25*5+0.25*0.25- 0.25*0.01)+(2+0.5+0.01+0.5*2+0.5*0.5+0.5*0.01+0.02*2+0.02*0.5+0.02*0.01)
=20.96+1.31+2.51+1.3052
=26.0852
